REPORT DATE: 07-22-2021 REPORT TIME: 0200 UTC REGION: GULF OF MEXICO SUB REGION: N/A AREA/BLOCK: GREEN CANYON 18 IMAGE DATE: 07-21-2021 IMAGE TIME: 2359 UTC DATA SOURCE: RADARSAT2 MODE: Standard HH RESOLUTION: 25 meter LOCATION: 27°57'52" N/91°03'30" W AREA: 35.38 square kilometers CONFIDENCE: Medium-High REMARKS: A possible oil slick was observed in satellite imagery. This anomaly is unconfirmed as oil. The segmented anomaly as a whole extends E for about 38.6 NMI in total length and 1.1 NMI as its widest point. The anomaly was linear in shape and showed a very strong contrast against the ocean background. A candidate vessel could be seen very close to the starting point of the anomaly for possible bilge dump or spill but the anomaly doesn’t appeared to be connected to the vessel. The winds near the time of the image were out of the SW around 10 kts. UNCERTAINTIES: The source of the anomaly is still uncertain but a candidate vessel can be seen very close to the anomaly Maps and shapefiles can be accessed at: www.ospo.noaa.gov/Products/ocean/marinepollution/ ERMA: https://erma.noaa.gov/gulfofmexico/erma.html#/layers=1+47644&x=-90.64415149999999&y=27.976832&z=11&panel=layer If you would like to share any feedback about this report or have questions, please contact the operational analyst at (301) 683-1403 or send to oceanmap@noaa.gov.
